maximum as compared to later sowings. Ganguly and Bhattacharya (2001) have noted
similar decisive effect of sowing time on chickpea growth and development and reported
reductions in various morpho-physiological attributes with delayed sowing due to less
favourable weather variables. There was significant variation in mean straw yield due to sowing
dates. The higher straw yield recorded by 15 th November sowing date, which was found to be
on par with sowing on 15 th December. The lowest straw yield (978 kg ha -1 ) recorded on 30 th
December.
The gross monetary returns were significantly influenced by different sowing dates.
Significantly higher gross monetary return (Rs 78938 ha -1 ) was obtained by crop sown at 15 th
November over rest of the sowing dates. The lowest value of gross monetary returns was
recorded on sowing time 30 th December (Rs 31273.91 ha -1 ). The net monetary return was
significantly influenced with sowing dates. The highest net monetary return (Rs 55846 ha -1 )
was recorded by 15 th sowing over rest of the sowing dates. The highest benefit: cost ratio (3.42)
was recorded at 15 th November sowing. The lowest value was recorded at 30 th December
sowing treatment.
Effect of varieties: There was statistically significant variation in seed yield due to varieties.
The highest grain yield (1460 kg ha -1 ) was recorded in variety RVG 203 which was found at
par with variety RVG
202. However lowest grain yield (1207 kg ha -1 ) was produced by variety AKG 70. Difference
in straw due to different varieties was significant. Variety RVG 203 recorded significantly higher
straw yield (1875 kg ha -1 ), which was at par with variety RVG 202, BDN 797, and Phule
Vikram. The lowest straw yield (1559 kg ha -1 ) observed in variety AKG 70. The cost of
cultivation for all varieties, was Rs. 23092 ha -1 . Chickpea variety RVG 203 significantly
recorded higher gross monetary returns of (Rs 66758 ha -1 ) as compared to remaining varieties.
The highest net monetary return (Rs 43666 ha -1 ) was recorded by RVG 203 variety over rest
of the varieties. The highest benefit: cost ratio (2.89) was recorded in RVG 203 variety at rest of
the varieties. The lowest value of benefit: cost ratio (2.41) was recorded in AKG 70. The
interaction effect between sowing dates and varieties were found to be non-significant in straw
yield, except in grain yield
